| Audio Research Tube AMP Reliability Well I havn't gotten in too many M-100 but if I do I know who to call...8o) | |
| Audio Research D-90 LOL I know Houseofsound no worries. I keep meaning to look at my D-90 diagram... | |
| First Tube Amp: Advice? Keep spare tubes on hand? Hate to be the fly in the ointment but there are some amps that require a resistor replacement before attempting to swap out the bad output tube. This depends on how the tube failed. Some manufacturers use these resistors like fuses. If the resist... | |
| Audio Research Tube AMP Reliability amperex? | |
| Audio Research D-90 Yessir...or me.. LOL newbie? | |
| Audio Research Tube AMP Reliability The M-100 run very hot you might want to put a fan on em. Can you still get the 7119's from ARC? | |
| Audio Research Tube AMP Reliability well I suggest you contact the people who worked on it to go through the amp again and check the amp for proper output at clipping as this doesn't make any sense... | |
| Audio Research Tube AMP Reliability That's a shame as the D125 is a very nice sounding amp. Being so far away from the U.S. makes it rather difficult to get parts/service etc. | |
| Audio Research Tube AMP Reliability Well your bias difference is odd..What did you mean by "blast". Did a tube arc? Bias can fluctuate depending on your line voltage and the accuracy of your volt meter. BTW its 65 mV not mA as you are measuring across a resistor not in series with t... | |
| Audio Research D-90 Just so you know the old caps may be twist-lock-lytics. If that is the case I usually replace them. You can usually read a date code off of them to see when they were manufactured. Twist-lock caps have a high degree of ESR or equivalent series res... | |
| Audio Research D-90 Houseofsound, Does your amp have the white body relay located near the main bank of filter caps? Let me know as I can contact the factory and get a bit of info for you. If your amp is sans relay no worries. G | |
| Audio Research D-90 Depending on the version of your D90 there is a relay that should probably be removed for reliability issues. It's been a while since I've worked on one and will have to check with the factory to find out if the relay is replaced with a thermistor... | |
| Audio Research Tube AMP Reliability Most people do not want to spend the money for ARC tubes as they are expensive. I won't fix an ARC amp unless I can use ARC tubes pure and simple. I have had way too many problems with tubes from other vendors and it becomes a huge headache. And y... | |
| Audio Research Tube AMP Reliability I repair ARC on the west coast...Non ARC output tubes are always a very bad idea and should never be used. | |
| Audio Research Tube AMP Reliability The biggest problem isn't the fault of ARC. They rate their 6550's life span to be approx 2-3000 hrs. That being said most people don't keep track of the time they put on their tubes. A few ARC amps have Hobbs Meters on them (elapsed time on the t... |
